Leon Balogun has emerged as a major fitness doubt for Rangers ahead of the trip to Celtic Park.

The defender - who was withdrawn at half time against Kilmarnock - is not fully fit for the huge title race clash this weekend.

Balogun had recently returned to the Rangers starting line-up after Connor Goldson was ruled out for the rest of the season.

However, he could now miss the huge match against Glasgow rivals Celtic at Parkhead tomorrow.

The Ibrox boss confirmed:Ā "Leon Balogun is doubtful, no other fresh injuries or players returning from injury."

On the defender after he was subbed off against Kilmarnock, Clement had said: "Yes he was injured that is why I had to replace him.

"I hope it is a small muscle injury.

"We will see in the next couple of days. But he struggled too much to continue."

Abdallah Sima and Rabbi Matondo won't be back to fitness for the Celtic match either.

However, Clement will be able to call upon Ben Davies who replaced Balogun last weekend and scored in the 4-1 win over Kilmarnock.

The centre back put his side ahead at Ibrox and appears set for a starting spot at Parkhead alongside John Souttar after the news on Balogun's fitness struggle.
